  3. 3. Green Is Good C oncern about the environment has become a focal point for consumers and business alike. Issues ranging from global warming to renewable other greenhouse gases. Production of electricity in electric plants requires fossil fuel combustion which contributes substantially to carbon dioxide energy resources, water quality, recycling, and emissions. Every day, toner-based printers and green building are no longer topics of discussion photocopiers in thousands of offices worldwide only among scientists or environmental protection contribute to environmental degradation by using agencies—they have become part of mainstream large amounts of energy and emitting carbon conversation all over the world. dioxide into the atmosphere. Initiatives like the U.S. Green Building Council’s Businesses and individuals have become aware of LEED® (Leadership in Energy and Environmental the need to replace their existing office equipment Design) Green Building Rating System™, and with energy-efficient models. This paper explains ENERGY STAR, a joint program of the U.S. the benefits of two of the more environmentally Environmental Protection Agency and the U.S. friendly printing technologies. Department of Energy, also serve to promote energy conservation and green practices. The Academy Award-winning movie, “An Inconvenient Truth,” placed the issue of global warming squarely on tens of thousands of theater and television screens, spurring even greater interest in protecting the environment. Companies looking to go green are examining every facet of their operations. The good news is that they can choose advanced printing technologies that offer conserve energy, reduce waste, and utilize environmentally friendly inks—and do their part to help protect the environment. Saving energy is not only good for business, it’s good for the planet. Energy consumption, including production of electricity, has a strong correlation to many environmental issues. Global warming is just one of those concerns. A majority of the scientific community agrees that the global climate is warming, due in large part to emissions of carbon dioxide and other greenhouse gases from human activities including industrial processes, fossil fuel combustion, and changes in land use. During the 21st century, this warming could result in additional sea-level rise that will gradually inundate coastal areas, change precipitation patterns, increase risk of droughts and floods, threaten biodiversity, and lead to a number of potential public health issues. To avoid the adverse effects of climate change, experts say that there must be a dramatic reduction in emissions of carbon dioxide and | RISO, Inc. | 3
  4. 4. Energy Savings Direct Energy Savings L ong known for their reliability and cost-efficient operation, digital duplicators are gaining recognition for their low energy consumption For producing full color documents, inkjet printer technology provides full color output with no heat. While inkjet printers use more electricity and unique heatless technology platform. than duplicators, they still use far less than toner- Digital duplicators employ a plate-based ink-on- based technologies. Typically, inkjet printing has paper technology that eliminates the extreme been reserved for small print quantities, but there heat and high power consumption required by are a limited number of high speed inkjet printers photocopiers and toner-based printers, offering on the market, such as the RISO HC5500, that an environmentally friendly alternative that is also are engineered for high volumes. The HC5500, significantly less expensive to operate. They require for example, easily handles monthly volumes of as little as 3.5 amps of electrical current and use 500,000 pages. about the same energy as four 100-watt light bulbs when producing copies. RISO digital duplicators have earned the ENERGY STAR for their low energy Related Energy Savings use; in a side-by-side comparison of a RISO digital A November 29, 2006 article in the Wall Street duplicator and an ENERGY STAR rated photocopier, Journal states that: “Air conditioning now represents the digital duplicator resulted in an astonishing 95% 60-70% of the energy costs at data centers.” This is cost savings over the photocopier. because data center printers create heat, for which Duplicators are an excellent choice for producing air conditioning is necessary to compensate (see monochrome or spot color output. They are ideal below). for volumes between 20 and 5,000 pages. In The lack of heat in duplicator and inkjet printing addition to saving energy, the new generation of eliminates the need for compensatory cooling, duplicators prints with unparalleled speed. For further reducing energy consumption and cost. This example, RISO’s RZ990 digital duplicator prints reduction in energy consumption in turn further one-color documents at 180 pages per minute, and reduces the carbon footprint—the amount of carbon the company’s MZ990 two-color/one-pass machine dioxide emitted through combustion of fossil fuels prints at 150 pages per minute. This technology has that leads to ozone depletion. advanced considerably since RISO first invented the Risograph digital duplicator in 1986. Reduced Power Consumption Frank Vain, production support manager for the Philadelphia Stock Exchange, installed RISO’s HC Series Full Color ComColor Printers in the Exchange’s new data center. In contrast to the 220-volt energy requirement of the old continuous-form feeders, the new inkjet printers can plug into standard 110-volt wall outlets. Because the HC Series technology platform does not use a heat and laser process, the units consume a fraction of the energy required to run heat-intensive devices. Additionally, no extra cooling is required for the facility. As a result, Vain estimates that the new printers have reduced power consumption by at least half. | RISO, Inc. | 4
  5. 5. Soy Inks D uplicators can use soy-based ink, which has several environmental advantages over petroleum-based ink. Soy ink does not release a significant amount of volatile organic compounds (VOCs) into the air as it dries. VOCs are chemical compounds that form smog at lower atmospheric levels. Soy ink is also more easily removed from paper during the paper recycling process, resulting in less paper fiber damage and more usable recycled paper. Additionally, the resulting waste is not hazardous and can be disposed of with no harmful environmental effects. RISO digital duplicator soy ink has received the SoySeal from the American Soybean Association. According to the association, soy ink can contribute to cleaner air, reduce dependence on foreign oil, and serve as a sustainable resource. RISO inks are non- flammable and UL classified. Use of Recycled Paper U nlike many other printing technologies, duplicators can print on many types of recycled paper. Printing on recycled paper has a multitude of environmental benefits when compared to virgin paper, it saves trees, energy, water, and landfill space. It produces less pollution, protects ecosystems, and needs less bleaching than virgin paper, thereby reducing the use of toxic chemicals. | RISO, Inc. | 5
  6. 6. Efficient Use of Supplies R ISO inks are designed to work with the RISO ink delivery system that uses a microprocessor to control the vacuum-drawn inking process, ensuring RISO also developed the i Quality System™—a technology that provides automatic two-way communication between the RISO digital duplicator that all the ink in the tube is consumed, thereby and its supplies (inks and masters) via tiny eliminating ink waste. Additionally, the ink emulsion integrated RF tags embedded in the ink bottle properties ensure that ink can be stored for long and master roll. The i Quality System continually periods of time with no separation or change in monitors the ambient properties of the digital viscosity, also eliminating ink waste. Reliable ink duplicator and its supplies to ensure the highest performance means that paper isn’t wasted with output quality in every print. Other functions of poor quality copies. the RISO i Quality System include alerts to users before any shortages in ink and masters occur, and prevention of improper loading of supplies, further reducing opportunities for wasted supplies. Reliability and Durability The heatless process also means higher reliability and durability, resulting in fewer maintenance calls that would require a technician to drive to the customer site for a repair job. In addition, long machine life reduces the amount of waste going into landfills. | RISO, Inc. | 6
  7. 7. A Commitment to the Environment RISO Kagaku Corporation, RISO, Inc.’s parent company, has focused on environmental issues for many years. In 1996, the company set up an Environmental Protection Department and in 1998 established the “RISO Environmental Charter” and “RISO Environmental Protection Principles.” The company actively promotes environmental protection in its daily corporate operations worldwide. This commitment to the environment is a core value, and is evident in the development of environmentally friendly printing technologies. Conclusion Reducing energy use and carbon emissions is beneficial for companies and the environment, making it a win-win opportunity for business and the global community. With an installed base of toner-based printers and copiers numbering in the millions, replacing even a portion of these machines with more environmentally friendly technology will have a substantially positive impact on the environment. According to the ENERGY STAR Web site, if all US offices switched their imaging equipment to ENERGY STAR qualified products, the US would save more than 15 million kWh and more than $1 billion dollars, or $0.09 per square foot of office space. It would also prevent the emission of over 30 million pounds of greenhouse gases. | RISO, Inc. | 7
